Abstract

Recently, with developments in the automotive industry, sound and vibration damping have a considerable attraction with a diversified customer needs and advanced automobile. In general, among various materials, textile materials, such as felt and glass fibers, polyurethane foam, and PET fiber materials were used to reduce sound and vibration of the automobile. These materials were located in various main parts of the automobile to block sound and vibration, resulting in a comfortable ride. In addition, to improve fuel economy, weight reduction and cost saving for the automobile were also being considered together as well as the reduction of sound and vibration of the automobile. Therefore, in this paper, we focused on the need of interior sound and vibration absorption materials in the automobile and absorption materials-related technologies.

최근 자동차 산업의 발전과 더불어 수요자의 요구가 다양화, 고급화됨에 따라 차량의 흡/차음에 대한 관심이 크게 증가하고 있다. 일반적으로 차내의 소음과 진동을 줄일 수 있도록 하기 위하여 섬유재료(펠트, 유리섬유), 폴리우레탄 foam, PET 섬유재료 등과 같은 소음진동 흡수재료를 사용되고 있다. 이러한 소음 진동을 위한 흡/차음재료들은 자동차에 장착되어 다양한 부분에서 발생하는 소음 및 진동을 차단하여 쾌적한 승차감을 주는 주요한 부품으로 자리잡고 있다. 또한, 차량의 소음 진동 제거를 위한 자동차용 흡/차음재료의 요구는 최근들어 더욱 높아지고 있으며 소음 진동 저감 이외에 연비개선을 위한 경량화, 비용절감 등도 함께 고려되고 있다. 따라서 본고에서는 자동차 내장 흡/차음재료의 필요성과 더불어 관련기술에 대하여 중심으로 살펴보도록 하겠다.
